The ship's captain recommends they go towards a tree on the top of a mountain instead of directly at their goal. Leorio takes the bus and the rest head towards the tree. The bus is a trap, so Leorio abandons it and catches up with Gon and Kurapika. Matthew, an examinee they meet, travels with them and then betrays them. They successfully answer a riddle asked by an examiner and move on to the next test.

Gon, Kurapika, and Leorio reach the first stage of the Hunter Exam, a seemingly endless forced run through a tunnel leading by the examiner named Satotz. They are befriended by Tonpa, a man taking the exam for the 35th time, and meet Killua, another entrant. In the end Tonpa betrays Leorio, as Gon and Kurapika go looking for them.
